本文實例講述了JS基於cookie實作來賓統計記錄訪客資訊的方法。分享給大家供大家參考。具體如下：
這裡使用JavaScript記錄訪客的來賓訊息，記錄是第幾次來訪，顯示的資訊有：您的名字;您瀏覽該網頁的次數;您上次瀏覽網頁的時間。可以更改姓名。
運作效果如下圖：
具體程式碼如下：
<html>
<head>
<title>记录客户信息</title>
<script language="JavaScript">
<!--
var expDays = 30;
var exp = new Date();
exp.setTime(exp.getTime() + (expDays*24*60*60*1000));
function Who(info){
var VisitorName = GetCookie('VisitorName')
if (VisitorName == null) {
VisitorName = prompt("请输入姓名：",'');
SetCookie ('VisitorName', VisitorName, exp);
}
return VisitorName;
}
function When(info){
var rightNow = new Date()
var WWHTime = 0;
WWHTime = GetCookie('WWhenH')
WWHTime = WWHTime * 1
